YesPlayer

YesPlayer is a video player that supports a ton of formats, like MP4, FLV, and MKV, among others. It also lets you load subtitles in different formats, like VTT, SRT, or SSA. And you can do all of this from a simple, convenient, and practical interface.

From the main tab in YesPlayer, you can see a complete list of all the videos you have stored on your smartphone's memory. All you have to do is tap on one of them to play it. The video will start playing automatically, and if you have subtitles, all you have to do is tap on the corresponding button and choose the version you want.

YesPlayer is a video player for Android that's both easy to use and lightweight. Because of this, it doesn't have as many features as other players like MX Player and VLC, but it's still a great way to watch all your videos without any complications.
